Default [Q] ZTE Z993 Prelude UNLOCK?

Does anyone have any ideas as to unlocking the ZTE Z993? I know they have unlocked bootloaders, Fastboot, There's even Root and Custom Recovery out there for this device... But I'm trying to determine a way to network unlock them... Perhaps through an engineering bootloader, flashable through fastboot?
